摘要：
The addition of BaO-ZnO-B2O3 (BZB) glass was proven to effectively reduce sintering temperature of BaTi5O11 ceramic from 1100 to 900 degrees C in the presence of the liquid phase while maintaining excellent microwave dielectric properties. Effects of BZB glass on the phase composition, wetting behavior, microstructure, activation energy, and microwave dielectric properties of BaTi5O11 ceramics were studied in detail to understand the basic mechanism of the low temperature sintering kinetics. The results revealed that the sintering process of BaTi5O11 was significantly promoted at a low temperature, owing to the existence of the liquid phase caused by BZB glass, which effectively lowers the activation energy, called liquid-phase sintering.
